Abstract
In Australia, surveillance data establish that there are higher rates of late HIV diagnoses among heterosexual migrants from Sub-Saharan Africa and new HIV diagnoses among gay and bisexual men (GBM) from Southeast and Northeast Asia and Latin America. Together, these groups are identified as priority migrant communities in current efforts to eliminate HIV transmissions. HIV health literacy is recognised as a key means of improving access to services and health outcomes. This qualitative paper explores critical HIV health literacy among priority migrant communities in Queensland, Australia. To foreground community voices, peer researchers from priority migrant communities participated in the project design, data collection and analysis, with 20 interviews completed. The findings demonstrate how participants' engagement with HIV health information and services is highly relational and situated within the framework of sexual health and wellbeing. Participants strategically selected where to seek information and who they trusted to help them appraise this information. They further demonstrated reflective capacities in identifying the contextual barriers that inhibit the development of their HIV health literacy. The findings highlight the need for HIV health promotion strategies that embrace a sex positive approach, promote cultural change, and involve collaboration with general practitioners (GPs).

Abstract
Polymorphisms of the CART gene were investigated by PCR-single-strand conformation polymorphism analysis in 540 samples from 10 goat breeds. Ten novel single-nucleotide polymorphisms as well as three microsatellites were detected; a mutation, 77T → C, led to an amino acid change (Leu → Ser). Associations between polymorphic loci and reproductive traits were analyzed in Chuandong White, Guizhou White and Gulin Ma breeds. Mutation at position 524 had no significant effect on litter size in these three goat breeds. The polymorphism 539C → A differed significantly among the three breeds (P < 0.05); C(7)T(8)/C(9)T(8) at 939 was associated with larger litter size (P < 0.05) than genotypes C(7)T(8)/C(7)T(8) and C(7)T(8)/C(8)T(8). No significant association of birth weight was found with gene variation (524C → T, 539C → A and 939 CnTn). These findings could be valuable for marker-assisted selection for goat breeding.

Abstract
Changes in heparin-binding fibroblast growth factor gene expression and receptor phenotype occur during liver regeneration and in hepatoma cells. The nucleotide sequence of complementary DNA predicts that three amino-terminal domain motifs, two juxtamembrane motifs, and two intracellular carboxyl-terminal domain motifs combine to form a minimum of 6 and potentially 12 homologous polypeptides that constitute the growth factor receptor family in a single human liver cell population. Amino-terminal variants consisted of two transmembrane molecules that contained three and two immunoglobulin-like disulfide loops, as well as a potential intracellular form of the receptor. The two intracellular juxtamembrane motifs differed in a potential serine-threonine kinase phosphorylation site. One carboxyl-terminal motif was a putative tyrosine kinase that contained potential tyrosine phosphorylation sites. The second carboxyl-terminal motif was probably not a tyrosine kinase and did not exhibit the same candidate carboxyl-terminal tyrosine phosphorylation sites.

Abstract
The differentiated human hepatoblastoma-derived cell line, HepG2, displayed two classes of specific membrane receptors for heparin-binding growth factor type 1 (HBGF-1). Specific membrane receptors were distinguished from nonreceptor heparin-like binding sites. Receptors with an apparent Kd of 9.2 +/- 0.9 pM and present at 15,000 +/- 900/cell correlated with HBGF-1 stimulation of HepG2 growth. Receptors with an apparent Kd of 2 +/- 0.4 nM and present at 180,000 +/- 18,000/cell correlated with inhibition of growth and changes in secretory products. Other hepatoma cell lines exhibited a simple positive mitogenic response to HBGF-1 and a single class of high affinity binding sites. HBGF-1 covalently cross-linked to hepatoma cell surface polypeptides of apparent mean molecular mass of 130 kilodaltons. At 37 degrees C, receptor-bound HBGF-1 was internalized (t 1/2 = 45 min) but not degraded for up to 6 h. The display of receptors decreased with increased cell density and expression of HBGF-1 mRNA and HBGF-1-like activity in the culture medium. Proliferating normal human hepatocytes also exhibited two classes of binding sites with affinities for HBGF-1 and apparent molecular weight similar to HepG2 cells. These results implicate HBGF-1 or homologues in human hepatoma cell growth and normal liver cell regeneration.
